I got some bird poop on my Z3 (steel gray) in an area that I did not notice it. It was probably there a few days before I washed it off. Now there is a noticeable area of the finish that still shows where the poop was. I used HD Cleanse from Zymol on it - MOST of it is gone, but not all of it. This is very disconcerting. I need help and suggestions from the list... please don't tell me my finish is ruined forever - I've only had the car for three months!
Thanks in advnace!
